Unusual error with PHP/Apache

[ThePsion5]

Hi guys, I'm testing out a crawler class that I wrote recently, and it's doing some strange things when I try to run it. A single file holds it and the related classes - It compiles correctly. However, when I add a test to the end like this:

print 'Starting...<br />';  $Test = new Crawler('www.google.com');  $Test->crawlSite();  print 'Ending...<br />';

Firefox tells me that the document contains no data...a.k.a. a blank screen. If i comment out the two lines where I declare and then run the crawler, then it mysteriously works fine. What exactly is happening here?EDIT: I fixed it now....for whatever reason I managed to send it into an infinite loop but it wasn't outputting each iteration, lol.
